I have been asked to add an ETHERNET port to an existing processor board that uses a TMS320F DSP. There is one unused UART port so I'm looking for a UART to ETHERNET module.
Several years back I used a Lantronix X-Port to accomplish the same thing, however this module was fairly expensive.
I found a couple of SPI based modules at Digi-Key for about $30 for example https://www.digikey.ca/product-detail/en/WIZ550IO/1278-1022-ND/4425703
so this is an option.
Found this one, great price https://en.usr.cn/RS232-serial-to-ethernet-converter-tcp-ip-module
Important criteria for this design:
1) Price
2) Availability, I want to avoid something that will be obsolete a year or two from now.
3) Ease of use.
Any suggestions?
